w l IMPRQ-YED MACHINE FOR CARBURETTING- ATMOSPHERIC AIR.

The Schedule referred to in these Letters Patent and making part of the same.

To all whom fit may concern:

Be it known that I, ARTHUR. BARBARIN, of the a certain new and useful Improvement in Machines for Carburetting Atmospheric Air; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the annexed drawing, making a part of this speciicatiom My invention consists principally in certain mechanical improvements, by which ordinary gas-holders can be instantly charged to' their i'ull containing-capacity with atmospheric air, without the use of pumps or other ordinary equivalent appliances; but

It also consists of a means to stai-t automatically a mechanism by which theliolders can be automaticallyA refilled when they shall become nearly exhausted, and which, when `this is eected, will instantly stop the operation of the said mechanism,-however often the exigency of the occasion may require the rehlling of the holder, without the aid or e'ven presence. of any person whatsoever.

Eurthermore, my invention consists of a means by which the air is carburetted only at the very moment before it is to be used, and in just sufficient volume to supply the burners in actual use.

This latter characteristic of my invention eifectually prevents all possi-ble chance of accident from an accumulated supply of highly inflammable gas, either from the occurrence of a tire, or in consequence of a leak in My invention will be better understood byreferplete forni, as when ready for use, at oneot' the'iig ures, while at' the other ligures it is explained by separate views of important parts of it, in a detached condition'. r

A is an ordinary metallic or other water-tank or cstern, to contain water or other liquid up to the dotted line b.

A' is a metallic or other bell or gas-holder, secured and supported above and wit-hin the tank A by means of veitical pillars a a a, ropes or chains e c e, pulleys fff, and weights g g y, as shown, in such manner as to have its lower end or mouth continually immersed below the upper surface of the liquid in the tank when in use, to prevent the escape of the compressed air in that direction.

ythe lstop-cock h isopen.

' This pipe, as will be seen at Figure 2, runs directly into the tank A, above the 'water-line b, and is provided with an upper opening, J, expanded in the form of a Tunnel, so as 'fo present a larger surface for the more iegularexit of the compressed air through said main pipe, when the Astop-cock h is open, under the action of the bell A, as it descends.

I is a support of that portion vof the main pipe Ii that is within the tank, and which, in order to facilitate the rapid ascent of the bell, is comparatively larger than any other section of the same.

K is a branch tube connecting with the main pipe H,'outside the tank, and having the saine diameter as the enlarged interior section of the said main pipey to which I have just referred.

This branch tube or pipe K is provided with a hol- 'low metallic head, m, perforations q q q, and stop-cock l, and is connected to the larger outside section or .part of' main pipe H, in order to snbserve the purpose of economy, and to dispense with the supplemental longer pipes, provided with stop-cocks or valves which, under -a different arrangement, it might become necessary to apply to the tank to accomplish the desired object;

but while I do not consider their employment requisite in the practice-of my invention, l reserve the right to use other pipes, with proper valves or stop-cocks, it' for any reason I shall consider such use desirable.

M is a large. stop-cock, provided with an -upwardlyprojecting gauged funnel-shaped opening, m', which may be applied anywhere on the -top of the bell A', through which air is admitted into said bell whenever it,(t.he stop-cock) is open, and the hell is raised by *l means of the crank o', rope or chain p p', and drum O.

As soon as this stop-cock M is opened and the elevation of the bell begins, the water in the tank'A performs the function ota piston with'follower, and hence creates a vacuum which causes the air to rush in and ll the hell as rapidly as itascends.

If an ordinary conical valve, hinge'd and adj usted in any suitable manner, be piaceri ou the inside surface of the top of' the bell A', so as to open inwardly, with proper appliances for securing it in position, the operation of raising the bell will be still simpler, since it will only be necessary, in that case, to revolve the drum and lift the bell to till it, by means of the natural pressure of the atmosphere, which will be brought into development by the vacuum induced by the elevation of the bell above the surface of the water. But it' the tube K, with its stop-cock I, or other equivalent device, be employed Without a stop-cock, M, or any other opening through the top of the bell A', and the stopcock l be turned .open to permit the bell to be lifted, the operation is reversed, for in this case it is thc bell which, with the assistance of' the water, a-.cts as a pis-l ton to create the suction requisite to till it with air, and not the water, but the filling will he as rapid as in the tirst case; and 'it' the stop-cock M, on the top ot' the. bell A, or the equivalent of that cock, be used to,

operate in combination or conjunction with the pipe K, and its appliances, the diameter of, these openings the carl)wetting-liquid, may be raised and equalized,

may be reduced to the size of that of one valve, iff desirable, and the charging of the bell with air will be equally as rapid as by the separate use of either of the'- two first-described devices. Consequently, I reserve the right to use both or only one of the said induction-pipes or openings, as circumstances may require.

n is a faucet to discharge the Water from the metal or other water-tank A.

R marks three or more small tubes, connect-ing, as shown, with the same main pipe H, and its continuation U, so as to form part of the same.

These small tubes are designed to' divide the large stream of air from the holder into small columns, in order that the same may be more effectively and rapidly heated, and dried by one or more vapor-burners S during very cold, rainy, or foggy weather, in order that the temperature of the air, before passing into to produce the same degree of illuminating-powerl in the light or lights at all times, without reference to the temperature of theoutside air or the character of the hydrocarbon-liquid that is employed.

S' is ayapor-burner .that is placedv beneath'the divisional tubes R, to heat the same when required, and which is supplied with gasoline to produce the vapor from the recipient or tanks, through the conduit-pipe t, when the stop-cock u is turned open.

U is a continuation of the main pipe H, from the said divisional pipes R, and connecting with the end c ofthe Siphon-formed tube c", which passes into the hollow oil-tight lamp-post V, (see Figure 6,) in such manner that the interior perforated end w of said tube shall be immersed inthe hydrocarbon contained in the said lamp-post, and hence conduct the air from the holder through the said hydrocarbon, and thus carburet or convert it into illuminating-gas to be used as wanted, through the agency of the stop-cock u", the point of 'ignition being at x.

The continuation or section of the pipe H, marked on the drawings by the letter U, may obviously be connected with any other recipient for the hydrocarbon, and produce the s'ame result as in the case of a lamp-post, and, indeed, to any other apparatus in which a supply of air is required to produce any other results.

Y is a carburetter, provided with two perforated diaphragms, a' a", as shown at Figure 5, c being the aperture through which the liquid is poured into the same, and fj" f the air-supply pipe, which is provided with a stop-cock, l, and is connected with the tube 3, and, by-means of that tube, to theforce-pump 11:", that is attached to the clock-work Z, seen at Figure 3, for the purpose hereinafter described.

Il.' is the cduction-pipe from the carburetter, which is provided with a stop-cock, 2, and is connected, as shown at Figure 1', to the tube 3, which, entering the tank A at 4, lrises perpendicularly above the surface of the water contained therein, and connects, at j', to the edge (being soldered thereto) ofthe funnel J, (see iig. 2,) and then, by a sudden iexure downwardly, passes below the upper surface of the water to a sufricient depth to prevent the compressed air in the holder from forcing the water that is in the tank through this pipe, and. itself-(the air) from escaping through the same. Y f

f 3 is a stop-cock in the tube 3.

5 5, shown at iig. 3, are the `supports of the clock-workZ, and 6, a rotary wheel of the clock, on which is secured a pin or crank, 7, to operate the piston of the pump x", throughthe agency ofthe eccentric 8 and the shaft- 8', the same being held in position hy eye-bolts 8 8".

9 (see. tig. 3) is a trigger, connected with theV ywheel of the clock-mechanism, arranged in such a manner upon the clock-frame, that its bow-shapedprojecting head 9 is always confined inside the elongated slot 10 in the correspondingly-formed eccentric 10', (see Figure 4,) which is secured in a vertical position on the top of the bell, at l1, or 'in such a manner i that it starts or stops the operationof the clock-work,

or of the piston of the pump, as the case may be, as Lshall hereafter more particularly point out.

Having described the manner in which the several parts of my invention are connected together, I proceed now to indicate the mode in which it can be applied to di'ercnt uses.

)Vhen a supply of air is to he carburetted, for a few hours consumption only, and the number of burners to be lighted is limited, and the room assigned for the apparatus will admit one that is large enough to contain the necessary quantity of airto supply the burners for the given time, an aerometer, constructed as herein described, with or without vapol burner S', may be employed without any other appendages; but if the room assigned to the apparatus is oi' limited dimension, and a large number of burners is to be lighted, or if, after practical experiment, an apparatus of any given capacity should prove insuillcient t0 supply the necessary quantum of carburetted air for the given or required time, it would be obviously necessary to use my supplementary mechanical arrangement-s for automatically refilling the holder A as often as the original supply therein shall be exhausted, in order to keep the lights continuously up or burning, and to obviate the necessity of having a watchman or other person iu attendance, to perform the work of replenishment by hand.

In such cases, however, the carburetter Y, the pipes f ff'. and h h',nu1st not be connected to the tube 3 3, and the continuation section U of the'lnain pipe H, instead of being connected with the lamppost V, as before described, must be connected to the carburetter Y, through the pipes ff f', so that the eduction-pipc h' h', instead oi' being connected to the tube 3, as shown on thedrawings, must be connected to the main pipe of the gas-burners, to supply them with gas when wanted. v

But should it be desirable to supply the holder A with gas instead of air, automatically, then the pipes f' f' j and yIt' h must remain connected to the carburetter Y and the tube 3 3, as shown on the drawings, l

to operate as hereinafter described.

\Vhen the first supply of air putin the holder A is used without the self-charging mechanism, or other equivalent appliance, the stop-cock M, on top of the bell A', and the stop-cock Zin tube K, when employed conjointly, must be opened. Any convenient means may be employed to do this.

Lhe drum 0 is then revolved, by means of the crank 0', to raise the bell, through the medium of the ropes p, which causes the air to rush through the valve M and` the tube K, into the bell, as the same rises upwardly.

If, when the bell attains its greatest point of elevation,'these valves are, automatically or otherwise, closed, and the bell be allowed to descend, by its own weight, into the water of the tank, the air therein contained will be at once compressed between the surface of the wat-er and the top of the-bell, from thence to be distributed through the carburetter for making gas, or ,to any other apparatus requiring a constant stream-of air, which stream may be regulated, or divided into smaller streams, if desired.

But when it becomes necessary to rell the airholder with air, by automatic action, Without disturbing the current ot' air escaping through the main pipe H, then the clock-work and eccentric 8, driven by a weight, are employed, in connection with the force-pump a", to force it in, through the pipe 3, which leads intothc4 tank, to` serve asa conduit for the same. y v I 'i In that case the stop-cocks l and 2 of the carburetter Y, when connected-to thetube 3, as shown on the drawing, are closed, and the stop-cock 3', which, it will be observed, is located between the pipes f and h', is opened, so that when the bell is nearly down, and before its vsupply of airis exhausted, the Vupper part of its vertical eccentric l0, fig. 4, imp inges against one side of the bow-shaped trigger 9 of the prnechanisrn, and releases its fly-wheel, which at once puts the air-pump in motion, and refills the holder with air that is driven into it through the tube 3. As the holder has attained to a fixed or certain .point of elevation, the lower part of the same eccenwheel, and thus stops its further rotation until the descent of the bell renews the operation just above described, and so on indefinitely, or until the clockwork ceases to operate.

Should it, however, be desired, automatically, to fill the reservoir with gas instead of air, then the stop-cock 3' must he closed, and the stop-cocks 1 and 2 opened, to allow. the air, under the action of -the pump, to pass through the Carburettor Y before entering the reservoir.

Instead'of employing the mechanism I have described to operate the forcelpnmp, I may sometimes use a steam-engine to do it, whilst replenishing the bell A', particularly in such localities where such engines are already in use during the night-time.

Under some conditions `I may use a hand-pump, iu connection with `my apparatus, and duplicate certain parts of the latter, if I-deem proper.

Having thus described my invention,

What I claim, and desire to secure by Letters Patent, is
